^ Hashimoto is only in charged of H!P overall
music production. His official position is the music director of H!P and Zetima label manager. (Rumor is that he is also the president of Up-Front Work, which oversee the overall music production in the UP-Front conglomerate.) Another big guy is Nishiguchi from UP-Front Promotion, which oversee talents production, so for H!P Nishiguchi involves in member auditions, training and etc. Tsunku sat above these two in H!P as the general producer to oversee both music and talent productions before he retired. From Hashimoto's words, there is no one replacing Tsunku at the moment. They assemble all staff and come up with directions. Of course, Hashimoto and Nishiguchi probably play important roles in the process.
v Agree and Agree. Tsunku was a super human because he also wrote most of the music in addition to overseeing both the music and the talent production.
